Old kids movie

I can not remember the name of this movie. I saw it in maybe 2005 but I’m sure that it was probably older than that. The kids have a club house (not The Little Rascals) it has like lights and a slide. I don’t remember most of what is in the movie but at the end I believe they burst into a town hall meeting with money to buy land for their club house and to keep an old man on his land.
